Ultrasonic welding machine and use method

Abstract

The invention discloses an ultrasonic welding machine. The ultrasonic welding machine comprises a microcomputer-controlled automatic circuit system, wherein the microcomputer-controlled automatic circuit system comprises an automatic frequency tracer; the microcomputer-controlled automatic circuit system presets a rated sound wave frequency; and in the case of too high or too low sound wave frequency of the ultrasonic welding machine during a use process, the automatic frequency tracer feeds back a signal into the microcomputer-controlled automatic circuit system, and the microcomputer-controlled automatic circuit system re-adjusts the sound wave frequency. According to the ultrasonic welding machine and a use method, the sound wave frequency is adjusted to adapt to the actual welding need of a workpiece through the automatic tracer of the microcomputer-controlled automatic circuit system, the automation of product machining is realized, and the working efficiency is increased; and a high welding speed and firm welding are achieved, and the welding strength is capable of approaching to the strength of a raw material.

Description

technical field [0001] The invention belongs to the technical field of welding machines, and in particular, the invention relates to an ultrasonic welding machine and a use method thereof. Background technique [0002] Ultrasonic plastic welding machine (English annotation Ultrasonic plastic welding machine) does not add any adhesives, fillers or solvents when welding plastic products, and does not consume a large amount of heat. It has the advantages of simple operation, fast welding speed, high welding strength, and production High efficiency and other advantages. Therefore, ultrasonic welding technology is more and more widely used. [0003] At present, the commonly used ultrasonic plastic welding machines on the market can convert the signal into high-frequency mechanical vibration through the energy conversion system, which is applied to the workpiece of plastic products, and the temperature transmitted to the interface is achieved through the friction between the surf...
